Dual WAN failover configuration which preserves web and voip links during switchover
We have Comcast cable highspeed commercial service and Verizon wireless backup in place. Using a Peplink router to monitor Comcast as priority WAN and switch to Verizon when health check fails. Problem is we lose web sessions that are open (such as Omnovia AV rooms and active downloads) and VOIP calls. Is it possible to set up both WANs to a common public IP address without the complexity of VPNs and be able to preserve the open session links so we don't lose voip calls and active web activity? Since we don't control the "other end" of the session on the open web, we cannot set up robust, fixed VPNs. Just need to understand if there are any protocols that support robust connectivity (RTP?).

I've used pfSense for years and it's a great product and works very well with multiple WANS. The software is free and they also have commercial support that is very reasonable in price. It also supports Cellular Air Cards for WAN connections though I would still recommend looking into a more reliable primary WAN and use the cable modem for failover and offset higher bandwidth traffic.
